海外，88X 分过的，考试时故意错了几个题。参考了坛子里多个版本 （alomar，lining7， romantictriv等），在这里一并感谢。 感觉Alomar的124Q是最好的，因为有截图。Romantictriv的125Q VCE适合考前练习，没有截图，不便于记忆。
1 N& P; u0 H8 [7 j( a$ |4 `% g$ z针对124Q的一些答案，我有自己的看法，在这里列出来，供后来者参考。记得是参考！！

; h8 m) G# r- j. GQ27. which statement about securing conneciton using MACsee is true?
这个比较纠结，答案F it provides network layer encryption on a wired network 显然是错的，应该是MAC layer的加密
0 ?* j6 P' O  M7 Q& ]+ L, {) n貌似可能的答案：
C. a switch use session keys to calculate encrypted packet ICV value..问题是，交换机是先decrypt packet之后再计算的ICV value
D. switch configured for MACSec can accept MACSec frame from the MACSec client. 考前我觉得应该是这个，因为A device that uses MACsec accepts either MACsec or non-MACsec frames, depending on the policy associated with the client.但考试的时候答案稍微不同，多了一个字：switch configured for MACSec can ＯNLY accept MACSec frame from the MACSec client.

Q41 which statement about Remote Triggerd Black Hoel
/ a' `! _7 G# g: m2 s/ r' s0 k/ kE. it drops malicious traffic at the customer edge router by forwading it to a Null0 interface

Q42 which statement about Cisco VSG functionality
4 h+ g( P# z( b9 u2 n; m: HE. it provides trusted access to VMs in an enterprise data center 其实这个答案也不太对，但别的的答案都是明显错，比如
A it allows..security administrator to author and manage port profile - 应该是network administrato才能管理port profile，所以不对
